|FEDERAL NATIONAL MORTGAGE ASSOCIATION FANNIE MAE filed this Form 10-Q on 05/06/2011|
income not recognized for loans on nonaccrual status because of a decline in the number of loans on nonaccrual status.
Guaranty Fee Income
Guaranty fee income increased in the first quarter of 2011 compared with the first quarter of 2010 due to an increase in the amortization of risk-based pricing adjustments.
Our average single-family guaranty book of business was relatively flat period over period despite our continued high market share because of the decline in U.S. residential mortgage debt outstanding. There were fewer new mortgage originations due to weakness in the housing market and an increase in liquidations due to the high level of foreclosures. Our estimated market share of new single-family mortgage-related securities issuances, which is based on publicly available data and excludes previously securitized mortgages, remained high at 48.6% for the first quarter of 2011.
Single-family credit-related expenses decreased in the first quarter of 2011 compared with the first quarter of 2010, primarily because our total single-family loss reserves increased less in the first quarter of 2011 compared with the first quarter of 2010.
Credit-related expenses and credit losses in the Single-Family business represent the substantial majority of our consolidated totals. We provide additional information on our credit-related expenses in Consolidated Results of OperationsCredit-Related Expenses.
